you can always downgrade to the last good known set of working packages,
either using old .debs on /var/cache/apt/archives, using testing
packages if suitable or simply using older snapshots of debian mirrors
:-)

yep, true... testing/unstable also means that programs may work
different as expected (ie: upgrading may require some work fiddling with
configs... on stable you don't have to fix anything if there's a new
package because it'll work exactly as before - except, of course, there
was a license violation or something like that which may remove
capabilities on some software).

Yeah, as I said before testing (sarge) becoming stable will come soon,
so unstable isn't as "interesting" as on some other occasions ;-)
(Experimental is not a full debian branch such as stable, testing or
unstable, ie: you can't install experimental. On experimental you can
find packages that, whether they fail, they'll definitely break your
system: libc, X, dpkg,... You don't want to use any experimental .deb
unless you're a debian developer ;-) )
And by the way you can always use testing and use "pinning" to get
software from unstable if you really want it, as the packages eventually
will be uploaded to testing :-)
